Definitions
- the present patent application relates to conditioning systems and methods for conditioning the air in an enclosed space, including, for example, a data center.
- a data center usually consists of computers and associated components operating 24 hours a day, 7 days a week.
- the electrical components in data centers produce a lot of heat, which needs to be removed from the space.
- Air-conditioning systems in data centers can consume as much as 40% of the total energy.
- air-side economizers runs outdoor air into the data center whenever outdoor air conditions are suitable to reject the heat from the data center.
- the air-side economizer can increase the risk of dust accumulation and air contaminants inside the space and may be limited to relatively cold and dry climates.
- the water-side economizer is usually a cooling tower which cools some or all of the return water in a chilled water loop.
- Water mineral deposition, micro-organisms and biofilm growth (e.g. Legionella bacteria), corrosion of metal components and other maintenance challenges in the tower are some of the drawbacks for the water-side economizer. Also, the water-side economizer application may be limited to relatively hot and dry climates.
- DEC direct evaporative coolers
- US2013/0283837A1 relates to an air conditioning system using outdoor air and having a first heat exchanger, an evaporator, a condenser, and a first fan disposed on the interior side; and a second heat exchanger and a second fan disposed on the exterior side.
- the system includes a first refrigerant for a compression-type refrigeration cycle and a second refrigerant for inducing heat exchange in the first heat exchanger with indoor air and inducing heat exchanger in the second heat exchanger with outdoor air.
- US 2014/260369A1 describes an air conditioning system according to the preamble of claim 1 and implicitly discloses an air conditioning method according to the preamble of claim 16.
- the inventor(s) recognize, among other things, an opportunity for improved performance in providing cooling to an enclosed space using a Liquid-to-Air Membrane Energy Exchanger (LAMEE) as an evaporative cooler and using the reduced-temperature water from the LAMEE to drive a liquid-to-air heat exchanger (LAHX) to cool the air recirculating through the space.
- LAMEE Liquid-to-Air Membrane Energy Exchanger
- LAHX liquid-to-air heat exchanger
- the inventor(s) also recognize an opportunity for improved performance by using a second LAHX to drop some of the heat picked up in the cooling fluid from the air recirculating through the space.
- a system for controlling conditions in an enclosed space includes a scavenger plenum configured to direct scavenger air from a scavenger inlet to a scavenger outlet and a process plenum sealed from the scavenger plenum and configured to direct process air from a process inlet to a process outlet
- the process inlet receives heated air from the enclosed space and the process outlet supplies cooled air to the space.
- the scavenger plenum and the scavenger air flowing there through can be a plenum that transports outdoor air (OA) from an OA inlet through/by a number of conditioning components and then exhausts the heated OA air through an OA outlet.
- the scavenger and process plenums are sealed from one another such that the scavenger and process air streams do not intermix with one another (other than ordinary leakage between the two plenums, if collocated).
- the conditioning system also includes a LAMEE.
- the LAMEE is arranged inside the scavenger plenum and is configured to use the scavenger air to evaporatively cool a first fluid flowing through the LAMEE.
- the temperature of the first cooling fluid at the outlet of the LAMEE is lower than the temperature of the fluid at the LAMEE inlet.
- the conditioning system includes a first liquid-to-air heat exchanger or LAHX (LAHX1) arranged inside the process plenum.
- LAHX1 directly and sensibly cools the heated air from the enclosed space to a supply air temperature using a second fluid flowing through the LAHX1.
- the example conditioning system also includes a second LAHX (LAHX2) arranged inside the scavenger plenum downstream of the LAMEE.
- the LAHX2 receives and cools the second cooling fluid heated by the LAHX1 using the scavenger air.
- the first fluid flowing through the LAMEE is the same as the second fluid flowing through LAHX1 and LAHX2, including, for example, the cooling fluid flowing through the LAMEE and through LAHX1 and LAHX2 being water.

- Examples according to this disclosure can have a number of benefits and/or advantages relative to other systems that condition the air in an enclosed space.
- the layout of components in the system may be easier to optimize compared to other systems, including systems with a wheel (for example, heat/sensible wheel).
- Wheel-based systems are generally limited to vertical or horizontal wheel configurations which fix the unit height or width and constrain air tunnel dimensions.
- Cooling coils or other LAHXs can be arranged in a variety of ways (vertical, horizontal, slanted, v-bank, multisegmented, etc.) in order to improve system performance (i.e. reduce face velocity on the coils) and/or to optimize the cabinet layout for size reduction, location of air connections and internal air flow paths.
- a system without a wheel can easily be made in standard size modules which can be stacked together to construct larger capacity units (i.e. two 200 kW units can be stacked together to make a 400 kW cooling unit). Additionally, including only a single cooling coil or other LAHX, in the process air flow can reduce the total pressure drop and fan power for this air stream, which, in turn, can provide significant reductions in annual energy consumption.
- Removing the wheel also eliminates potential concerns some customers may have with this type of component, including, for example, wheel air leakage, maintenance, moving parts, corrosion of the wheel media, etcetera.
- the process air fan can be moved upstream of the process-side LAHX, which, in turn, can provide a measure of passive rejection of some of the fan heat.
- examples according to the present invention include integration of a liquid cooling coil or other LAHX downstream of the LAMEE in the scavenger plenum, which can cool the heated water before entering the LAMEE and can boost the system performance.
- LAHX2 can work as an economizer for the cooling system. Whenever the outdoor air is cold enough to cool the water to a set point temperature, water can bypass the LAMEE and only pass though the scavenger-side LAHX2 before returning to the process-side LAHX1 to cool the air recirculating through the enclosed space.
- the economizer mode can expand the life of the LAMEE and can save water, as little to no water evaporates when the system operates in the economizer mode.

- the pre-cooler conditions the scavenger air before it enters the LAMEE.
- Conditioning systems in accordance with this disclosure can also include one or more bypass dampers.

- LAMEE 108 or other such devices can offer advantages over conventional cooling systems, such as cooling towers, for example.
- the membrane separation layer in the LAMEE can reduce maintenance, can eliminate the requirement for chemical treatments, and can reduce the potential for contaminant transfer to the liquid loop.
- the use of LAMEEs along with an upstream and/or downstream cooling coil (or other LAHX) can result in a lower temperature of the water leaving the LAMEE and a higher cooling potential.
- Various configurations of cooling systems having a LAMEE are described herein and can boost performance in many climates.

- Pump 204 which can be controlled by system controller 150, pumps the cooled fluid from storage tank 202 into LAHX1110, by which LAHX1110 cools the process air supplied to the enclosed space. After the fluid provides cooling to the process air, the fluid can be recirculated back to LAMEE 108. The fluid will be at an increased-temperature or "heated" when it exits LAHX1 110, because the rejected heat from the process air has been picked up by the fluid.

- the scavenger air can then pass through LAHX2 112 and thereby cool the heated fluid received by LAHX2 from LAHX1 110.
- Conditioning system 300 can allow for three operating modes and selection of the mode can depend, in part, on the outdoor air conditions and a cooling load for the system 300.
- the cooling system 300 can operate in a first mode, an economizer mode, and the pre-cooler 302 and the LAMEE 108 can be bypassed.
- This economizer or winter mode can be as similarly described above in reference to FIG. 1 .
